Very cool temperatures over most of the Northland today with highs only in the 50s near Lake Superior and in far northeast Minnesota but it was a lot warmer in far southern portions of the area with highs today in the 70s to around 80 degrees from Hinckley and Siren, east to the Hayward Lakes area. Skies were generally overcast today but there was some clearing at times in parts of far eastern Minnesota and northwest Wisconsin. There was some fog and drizzle occurring near Lake Superior thanks to the humid flow off Lake Superior. Scattered showers have also occurred today in parts of Northland.
Low pressure across north central Wisconsin late this afternoon will drop south/east through Thursday evening -- An inverted trough extending west of that low through the northern half of Minnesota will basically washout by Thursday. An upper level low over the Manitoba Lakes region this afternoon will dig south/east into the Northland through Thursday before it moves into eastern Canada and away from our area Friday.
A chilly airmass will remain over the area into Thursday with the coolest temperatures found near Lake Superior where a brisk NE wind will continue tonight and Thursday morning, winds near the lake become more northerly during the day Thursday. Areas of fog and drizzle near Lake Superior tonight with scattered rain showers possible over the rest of the area, a few rain showers are also possible Thursday under mostly cloudy or partly sunny skies.
Lows tonight in the mid 40s to low 50s; Highs Thursday in the 60s over western areas with 50s to around 60 elsewhere. Early Friday morning has the potential to be a chilly one with lows possibly dipping into the 30s over interior portions of northeast Minnesota, lows over the rest of the area will range from the 40s to lower 50s.
Note: Can't totally rule out a bit of patchy frost in the typical cold spots away from Lake Superior in northeast Minnesota between 3-6 AM Friday but this chance is quite low.
Will warm up Friday as winds turn to the southwest as high pressure shifts off to the east -- highs will be in the 70s (Near average for mid July)
A cold front moves through the Northland Saturday. Warm air and moisture will build south of this boundary with highs over east central Minnesota and northwest Wisconsin in the 80s while dew points climb into the 60s. Not as warm and certainly less humid north of this front over northern Minnesota with highs Saturday in the 70s.
Note: The overall weather pattern through next week (July 21st) isn't favorable for any long lasting heat for our area -- There will likely be a couple days of warm and possibly muggy weather through next week, but these conditions likely won't last more than a day or two at a time before relief in the form of a lake wind and or cold front occurs.
